The Canistel or Egg Fruit is quite a common fruit in the Philippines where many other fruits of South American origin can also be found, no doubt introduced by the Spanish in the old days. In other Asian countries it is a rather rare curiousity. In the Philippines it's called Tiessa or Tisa or Chessa, another English names is Yellow Sapote as it belongs to the Sapote family or Sapotaceae. The species name is Pouteria camphechiana. In Malaysia where it seems to be a rather new introduction it's variously called Buah Mentega or Buah Lemak (meaning "Butter Fruit" or "Creamy Fruit" respectively). The ripe fruits are yellow and waxy skinned with a pulp that has the consistency of a hard-boiled egg yolk, hence its other name. The green fruit contain a sticky latex which disappear or at least lessen when the fruit is soft and fully ripe . Fruits can be highly variable in size and shape--ranging from round to pointed and ovaloid. They are usually eaten fresh out of hand but can also be used in custards, pies, milkshakes and other desserts.
